Response Time as a Proxy for Decision Confidence
This study explores the use of response time (RT) data in type-2 receiver operating characteristic (ROC) analysis, a method traditionally used to examine the relationship between confidence and response correctness. Analyses of 16 perceptual decision-making datasets revealed that: (1) RT data contains roughly two-thirds as much information about response correctness as confidence; (2) RT carries unique predictive power for response correctness, i…
Aphantasia modulates immersion experience but not eye fixation patterns during story reading
Consensus Goals in the Field of Visual Metacognition
Despite the tangible progress in psychological and cognitive sciences over the last several years, these disciplines still trail other more mature sciences in identifying the most important questions that need to be solved. Reaching such consensus could lead to greater synergy across different laboratories, faster progress, and increased focus on solving important problems rather than pursuing isolated, niche efforts. Here, 26 researchers from th…
What Is Consciousness, and Could Machines Have It
The controversial question of whether machines may ever be conscious must be based on a careful consideration of how consciousness arises in the only physical system that undoubtedly possesses it: the human brain. We suggest that the word “consciousness” conflates two different types of information-processing computations in the brain: the selection of information for global broadcasting, thus making it flexibly available for computation and repo…

Understanding the Higher-Order Approach to Consciousness
The higher-order theory (HOT) of consciousness has often been misunderstood by critics. Here, we clarify its position on several issues, and distinguish it from other views, such as the global workspace theory (GWT) and early sensory models (e.g., first-order local recurrency theories). For example, HOT has been criticized for overintellectualizing consciousness. We show that, while higher-order states are cognitively assembled, the requirements …
Opportunities and challenges for a maturing science of consciousness
The effects of neurochemical balance in the anterior cingulate cortex and dorsolateral prefrontal cortex on volitional control under irrelevant distraction
What is consciousness, and could machines have it?
The controversial question of whether machines may ever be conscious must be based on a careful consideration of how consciousness arises in the only physical system that undoubtedly possesses it: the human brain. We suggest that the word “consciousness” conflates two different types of information-processing computations in the brain: the selection of information for global broadcasting, thus making it flexibly available for computation and repo…

Reporting on the temporal properties of visual events masked with continuous flash suppression
How to measure metacognition
The ability to recognize one's own successful cognitive processing, in e.g., perceptual or memory tasks, is often referred to as metacognition. How should we quantitatively measure such ability? Here we focus on a class of measures that assess the correspondence between trial-by-trial accuracy and one's own confidence. In general, for healthy subjects endowed with metacognitive sensitivity, when one is confident, one is more likely to be correct.…
A signal detection theoretic approach for estimating metacognitive sensitivity from confidence ratings
Empirical support for higher-order theories of conscious awareness
Direct assessment of qualia in a blindsight participant
Relative blindsight in normal observers and the neural correlate of visual consciousness
By using a paradigm based on metacontrast masking, we created experimental conditions in which the subjective report of consciousness differs but the objectively measured ability to discriminate visual targets does not. This approach allowed us to study the neural correlate of consciousness while having performance levels carefully matched in healthy human subjects. A comparison of the neural activity associated with these conditions as measured …
